I found that after creating a Layer from a KML datasource and creating 
a feature based on the Layer definition, Feature->SetField() can be 
used to set pre-existing 'Name' ad 'Description' fields.

Reading the documentation and examples regarding FeatureDefn and 
FieldDefn still leaves me puzzled

I put two sample perl scripts on Trac under code snippets
Feedback is welcome
